Fleabane

 

(Pulicaria), a genus of plants of the family Compositae. The plants are annual or perennial herbs. The anthodia are gathered in racemose or peltate clusters. There are approximately 50 species in Europe, Asia, and Africa, primarily in the Mediterranean countries. In the USSR there are five species. Fleabane (Pulicaria prostrata) grows in moist meadows, along the banks of rivers and lakes, in ditches, in irrigation ditches, and along roads. It is a folk remedy used for intestinal disturbances and as a remedy against fleas (hence the name). P. odora is cultivated as a vegetable.

Sometimes the name “fleabane” also refers to flea plantain (Plantago psyllium), the seeds of which are called flea seeds.
